G'day perl-diddler,

Your problem may be related to which package is current. The error shows "$URL::Cacheable::pkg_host_mask" but your code only uses "$pkg_host_mask" and the current package is not indicated.

What's "P()"? It looks like some sort of wrapper around printf but that's just a guess.

Where does the following statement occur? 

$pkg_host_base = ($p->host =~ m{($pkg_host_mask)}) [0];

Unrelated to your current problem, but you have a redundant level of parentheses in that code. I foresee a future SoPW like "Why is this matching twice?". 

$ perl -Mstrict -Mwarnings -E '
    my $host = q{a.b.c};
    my $re = qr{([a-zA-Z][-a-zA-Z0-9]*\.[a-zA-Z]+)$};
    my $base = ($host =~ $re)[0];       # How I might have written it
    say $base;
    $base = ($host =~ m{($re)}) [0];    # How you wrote it
    say $base;
    $base = ($host =~ m{($re)}) [1];    # Fodder for another SoPW
    say $base;
'
b.c
b.c
b.c

The error has "at ./crawl.pl line 385". Have you posted that line? If so, which is it?

That may be enough for you to resolve your issue. If not, please provide the requested information.
